Effect of Bending Vibration Damper on Properties of Torsional

A model torsional bending vibration damper is proposed,and the amplitude of the crankshaft with the torsional bending vibration damper pully is deduced in this paper.Effect of parameters of bending vibration damper on the properties of torsional vibration reduction for torsional/bending vibration damper is studied theoretically and experimentally.When the parameters of torsional vibration damper are constant,the response of the crankshaft always passes a constant point with vary of the coefficient of the damp of the bending vibration damper.When the parameters of bending vibration damper are constant,the response of the crankshaft always passes two constant points with vary of the coefficient of damp of the torsional vibration damper.The problem of optimum in designing of torsional bending vibration damper is analysised and discussed.
